Comimark 1Pcs 1.5v~12v Battery Capacity Meter Discharge Tester 18650 li-ion Lithium Lead-Acid
Instructions:1. The first test should be fully charged battery.2. Connect the
battery to be tested positive to positive input, a negative input to the
negative, can not be reversed (with load reversal may damage the circuit)!
Load connected to the output of the positive and negative output, to work
through the tester micro USB power supply (not available desktop or laptop USB
powered), then the battery voltage.3. Direct start test need only one press of
the "OK" button, the tester can automatically develop an appropriate
termination voltage of the battery full charge voltage, and will start
flashing after the test three times. Need to develop artificial termination
voltage only when the battery voltage display state by pressing "+" or "-"
buttons to modify the termination voltage display beginning with P, behind the
representative voltage resolution 0.1V, set up after pressing the "OK "start
testing.4. After the start of the test the tester will control the load of the
electronic switch is turned on, the test data shows that the process will
release capacity (Ah), current discharge current (A) and battery voltage (V)
between the wheel was. When the battery voltage reaches the set cut-off
voltage, load control switches off the tester display data stays in capacity
(Ah) and above and the corresponding indicator flashes quickly together, now
displays the actual capacity of the battery is discharging capacity, about the
press "OK" to terminate flashing allows stable data display, press again "OK"
button to return to the power-on state can just replace the battery test the
next section ......¡¡Error codes and their meanings:Err1: battery voltage is
above 15VErr2: battery voltage is lower than the termination voltageErr3:
Battery can not afford to load or discharge current line too much
resistanceErr4: overcurrent (current exceeds 3.1A)¡¡
